configuration of the Fortimanager-VM is deleted after rebooting the server

[kh_atta]

we have a forrtiManager as a VM, we installed it in our network and after finished from it's configuration, then the server is rebooted after that and all the configuration on the fortiManager is deleted, we tried many time to restore our backup files but nothing restored,

any idea for this issue ?!

Is it a fully licensed FMG or evaluation 14-days installation? Do you have all the partitions present after reboot that were present before the reboot?

[kh_atta]

Yes, it fully license, and the partition the same after and before the reboot.

Then you have a very strange problem I haven't seen with FMG, sounds like a TAC ticket.
